The Norwegian Nobel Committee has accepted the nomination of the UGTT labor union for its peace award, according to the union.

The union was nominated by the presidents of four major Tunisian universities a few days after the adoption of the Tunisian constitution on January 2014, according to Huffington Post Maghreb.

The UGTT was one of four civil society organizations brokering political negotiations that helped end a months-long political deadlock after the assassination of assembly member Mohamed Brahmi in July 2013. Itâ€™s head, Houcine Abassi, personally met with Tunisiaâ€™s political leaders dozens of times over the course of talks.

These efforts eventually contributed to the ratification of Tunisiaâ€™s post-revolution constitution and the formation of a caretaker government tasked with seeing the country through to future elections.

The UGTT said its nomination was due to â€œthe leading roleâ€ it played in â€œthe defense of the values of freedom, democracy, and peaceâ€ and its â€œeffective contribution throughout its history in defending [Tunisia]â€.

The union, founded in 1946, played a key role in Tunisiaâ€™s struggle against French colonialism.
